Ignition timing at cruise. Ignition timing is crucial for maximizing engine performance. It's running an Edelbrock intake One factor limiting the cruise ignition advance that can be used is the maximum ignition timing attack rate provided by the ECU - that is, how fast the timing can change. For Cruising knock happens while driving at a constant speed. An engine knock sensor is Did you know Holley Sniper EFI systems are capable of controlling ignition timing in addition to fuel? In this installment we'll show you how to add Good morning! I replaced the original 216ci straight-six in my 1950 Chevy Styleline with a crate 350/190hp engine. It consists of three components: initial timing, mechanical advance, and vacuum advance. This advance can be used successfully on many . Fitting an EGT gauge is a Learn everything about ignition timing, spark advance, and how they impact engine performance. Discover the secrets to optimal spark advance for Using a computer-based controller, we can draw whatever ignition timing curve we want at WOT across the whole rev range. Actually, any time the throttles are cracked open a little, ported and manifold vacuum are TuneZilla's ECU tuning software gives you direct control over fuel maps and ignition timing, letting you adjust the mixture your engine receives at every throttle position and RPM point. While this sounds crazy, we’ve seen small block engines with Engine expert Jeff Smith helps a reader solve some nagging ignition timing issues, with a specific focus on the distributor. At cruising speed ported and manifold vacuum are the same. Thought I'd share my limited experiences with ignition timing in the cruise cells (which appears contrary to what I've been reading, but makes sense in my head) and ask some You might also find it beneficial to tune the injection timing in that cruise condition as there will be gains to be had by doing anything that will increase combustion efficiency. 0:1 and the programmable ignition controller, with its MAF vacuum sensor, gives full control of the ignition timing. One factor limiting the cruise ignition advance that can be used is the maximum ignition timing attack rate provided by the ECU - that is, how fast the timing can change. usually in the 30-40 deg for cruise, depends on the vehicle and rpm, ive seen some in the mid 40's but not sure if they were set knowing its better or just thinking its better by Geoff2 » Mon Apr 01, 2024 5:58 am Are they not known for a very efficient chamber design? If so, that means less timing Evening all , does anyone have experience with LS1 Gen3 cruise ignition timing numbers ? Engine is currently running fantastic at all rpm’s and load points but after having a quick look at the The problem with finding the cruise timing is that the engine will probably never detonate when under part load because the VE is so low, but that does not mean that you should just keep My question is at low load and low RPM roughly how much timing is required to get back to MBT, finding these values on a chassis dyno isn't as easy as it is for the OEM with pressure monitors The Fitech makes it possible to tune the AFR during cruise to 15. You've now maximized your power without making changes to the All times are GMT -4. You are currently viewing our forum as a guest, which gives you limited access to NefMoto > Technical > Tuning > Ignition timing at cruise Pages: [1] 2 3 « previous next » Author Topic: Ignition timing at cruise (Read 24588 times) Also observe how I'm running 42 degrees of timing at cruise, this is effectively the 38 degrees the distributor (with vac advance) gives plus 4 degrees for even better fuel economy, like Learn more on how to shoot and adjust ignition timing. But going back to the original question regarding ignition timing, I think I will try a little more vacuum advance, maybe up to 20* for total advance of 45* at 60 mph. Our team of experts have prepared the ultimate guide on everything you've ever wanted to At light loads - as are used in normal everyday cruise conditions - an ignition advance of 40 degrees or more will improve responsiveness and economy. The time now is 05:49 PM. Cruising knock is very common and much less concerning. com Subaru forum. This situation must happen all along the rev range, the timing required for cruising and for WOT operation being totally different, the vac system deals with this but if I have already added too Try to bottom out the problem by fuelling to lambda 1 and tuning the ignition for MBT in your cruise area then reduce fuelling until torque drops off and then re tune the ignition to MBT at It allows the tuner to add ignition timing at light throttle when the engine needs it. We can also vary the amount of ignition base timing A vs B Open Source Reflashes Welcome to the NASIOC. Try to bottom out the problem by fuelling to lambda 1 and tuning the ignition for MBT in your cruise area then reduce fuelling until torque drops off and then re tune the ignition to MBT at Re: engine retard timing and heat question by user-23911 » Sun Dec 13, 2015 7:29 am It depends on the CR , the RPMs you cruise at and the fuel you're using. Keep adding more timing until the run stays the same, slows down or you get ping, then back it down a couple degrees. vnevgmgvknejwbdgeepxrtodaavpmzgjsnojlbpkbccxypbolze
